我国位于环太平洋和欧亚地震带之间,华北、西北、西南、东南沿海等许多地区正处于地震频发带上,地震导致的死亡人数占洪水、泥石流等自然灾害死亡人数的一半以上,因此在建筑工程中必须保证建筑结构的抗震能力。文章在论述建筑结构抗震设计原则的基础上,分析了基于建筑结构整体性和抗震能力的常见加固技术,并提出了抗震加固中需要注意的问题。 China is located between the Pacific Rim and the Eurasian Seismic Belt. Many areas in North China, Northwest China, Southwest China and the southeast China are under frequent earthquakes. The death toll from earthquakes accounts for more than half of the natural disasters such as floods and landslides. Therefore, In the construction of buildings must ensure the seismic capacity of the building. Based on the principle of aseismic design of building structure, the article analyzes the common reinforcement technology based on the structural integrity and seismic capacity of buildings, and puts forward the problems needing attention in seismic strengthening.
